RAIL J'O'INT.

Application filed June 2, 1924. SeriaI No. 717,362.

To all whom t may conce/ra.'

Be it known that I, TWILLIAM G. IVILsoN, a citizen of the: United States, residing at lVest New Brighton, Staten Island, in the county ot Richmond and State of New York, have invented new and useful Improvements in Rail Joints, ot which the following is a specification.

This invention relates yto rail joints and is an improvement over my application Serial No. 635,682 allowed December 13th, 1923.

The principal object ot the invention is the provision of a rail joint whereby the creeping of the rail caused by the direction of tra-vel ot the rolling stock thereover will cause the rails to be moved into closer contact with the joint and their supporting ties.

Another object of the invention is to provide a rail joint which will creep with the rails for a predetermined distance, and after reaching the limit of movement, will coact with the ties to effect a tighter joint.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement ot parts, the essential features oit' which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a pair of rails provided with my improved rail joint prior to creeping of the same.

Figure 2 is a similar view but showing` the position of the parts after the rails have crept a predetermined distance. j

Figure 3 is a bottom plan view.

Figure 4; is a transverse sectional view on the line i-Ji of Figure 1.

Figure 5 is a perspective view of one of the joint sections.

Referring more particularly to the drawing, the reference numerals 10, 10 designate the meeting ends of a pair ot' rails which are connected together by a joint 11 ot' the construction shown in my co-pendingr application above referred to. The rail joint 11 includes a pair of identical sections 12 and 13, each of which comprises an angle bar let having a chair 15 arranged centrally thereof and depending therefrom. Fach chair 15 includes end walls 16 and side walls 17. The endwalls 16 are each formed with a prong 18 having a lower horizontal face 19 and a beveled or inclined face 2O which. meets the horizontal tace to form a suitable point. ri`he twosections are secured to the rail oints by the usual bolts and nuts 21 and the railsv are held down upon the ties by spikes Q2. A bolt 23 passes through the side walls 16 when the chairs are in their respective positions and serves to anchor the sections beneath the rails centrally of the joint.

When the joint sections: are applied, the same are positioned so that the chairs depend between two ties, the ties being spaced so that the prongs are arranged in close proximity thereto as shown in Figure 1 of the drawing whereby any tendency of the joint to creep in either direction will only cause the prongs at one end ot the chairs to penetrate the sides of the ties. Then the prongs penetrate the ties, the` inclined or beveled face 2O will tend to set-up a wedging action sufficient to cause the rails to move into closer contact with the ties and will also cause the joint sections to bear down into closer engagement with the rails.

From the foregoing description, it wiil be seen that when the rails creep by reason of the rolling,` stock traveling in one direction, the joint may only move a predetermined distance wherein it will stop as thc end walls 16 and the prongs 18 will co-act with the ties to iorm a barrier. In Figure 1 oi' the drawing, there is shown a. view prior to the creeping of the joint and in Figure 2 a view of the joint after the same has crept due to the rolling; stock travelling; in the direction of the arrow. It will, of course, be understood that it' the travelling of the rolling` stock was in an opposite direction to the arrow, the yprongs on the opposite ends of the chairs would penetrate the opposite ties.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing; from the spirit of my invention, and I therefore do not limit myself to 'the exact details of construct-ion herein set forth nor to anything' less than the whole of my invention limited only by the appended claims.

lhat is claimed as new is 1. The combination with the meeting ends of a pair of rails, a joint therefor including a pair of sections each having a depending chair intermedi-ete: its ends, ies

for supporting` said rails, seid chairs inten' posed between two of the ties, and means Carried by said Chairs for penetration in Jdie ties upon the creeping of 'the joint in either direction. n

2. The combination with the meeting ends of e pair of rails. of n vjoint therefor including a pair of sections each having` spaced depending walls, ties `for supporting' said rails, e prong' formed on each of said Weils, seid Wells beingr 'disposed in 'close proximity to said ties, whereby Creeping of the rails: in "either direction will Cause Certain of che prongs to enter one of the ties to move ythe parts into Closer cohteet with the ties.

3. The combination with the meeting ends of :L p'ai'r of rails., supporting ties therefor, means for eoi'lneeting the ends of said rails togeher, and means for moving said rails ini-o Closer Centuet with said ties upon the Creeping` of seid rails in either d ire etion.

n testimony wi'iereof I have eiiixed my signature.
